Throughout the Collins property, there are numerous secret chambers, dungeons, panels, passageways, rooms, and staircases.
Behind the bookcase in the Old House parlour, there is a secret room which in 1796 was used to hide a wounded Victoria while she was fleeing from the authorities. Earlier in her time span she had been held captive there by Matthew Morgan after he killed Bill Malloy. Barnabas would later keep his coffin there after he was awakened by Willie Loomis.
In the cell in the basement of the Old House there is a secret passage which leads out to a cave on the beach that Maggie used to escape Barnabas after she refused to be his bride. In the same cell there is a secret chamber where Barnabas had Willie hide some of his jewels.
It is revealed in 781 that there are a total of four secret rooms or passages in the Old House.
Behind the gravemarker of Naomi Collins in the Collins Family Mausoleom at Eagle Hill Cemetary there is a door which leads to the secret room once used to hide the family jewels and ammunition during the revolutionary war. It was used on various occasions to hide Victoria and Peter Bradford, contained Barnabas' coffin from 1796 to 1966, trapped David, housed Maggie when Willie kidnapped her, and hid Chris Jennings when he turned into the Werewolf.
The secret panel in the Drawing room makes its first appearance when Roger searches for Vicki in the West Wing . He touches a button on the cabinet next to the panel to open it. Roger navigates through the dusty corridors, down steps, then up a spiral staircase and comes out on the other side of the room that Vicki is locked in. (88 )
David and Amy also repeatedly use the secret panel in the drawing room to sneak visits with Quentin in the west wing. In these episodes the panel is opened simply by pulling on it. Quentin is able to exit from the secret panel into the drawing room in order to quietly sneak up on Ezra Braithwaite (685). Elizabeth states that the secret panel leads to the west wing but that it "has not been used in years" (692).
In a supply room in the west wing there is a door hidden behind a secret panel which leads to the room housing the spirits of Quentin and Beth Chavez. It also contains the gramaphone which would announce Quentin's presence.
It is revealed that there is a secret passageway in the room that Josette , Vicki , and Maggie shared. There is a door to the right of the fireplace which leads outside of the mansion. Barnabas uses this in order to secretly visit Josette in the days leading up to her death.
The playroom was a secret room that would appear and disappear at random. No records existed of it in the family ledgers, and entrance to the room was only possible when a musical carousel played its tune . A hidden door at the back of the room led to the Stairway into Time created by Quentin.
